The AirDog 4G 150GPH A4SPBC188 is the original proven Air/Fuel Separation Duramax lift pump or Fuel Preporator. A lift pump system is a must have for your 2001-2010 6.6L Duramax diesel. The fuel system on your Duramax diesel truck is the heart of the vehicle’s performance and reliability. This low pressure (8-10 psi) Duramax lift pump mounts to the inner frame rail using the supplied sandwich plate mounting system. The pressure side connects to the factory fuel line that feeds the CP3 injection pump. The suction/fuel supply side connects to the 1/2″ draw straw suction tube that is installed in the top of the fuel tank. Due to the fact the Duramax does not have a factory lift pump, these trucks usually see the most benefit from an AirDog lift pump fuel system.
The AirDog FP150-4G Duramax fuel pump incorporates the proven, quiet, and reliable 4G motor featured in the AirDog II systems. This 4-bearing motor technology is paired with the original FP high flow return base and pump assembly to maintain the proven benefits and features of the Original AirDog model.
